Error of Issac gym official document example code

I am following Issacgym official tutorial to program a ball in the simulation environment. The program can run with errors as followed:

[Error] [carb.gym.plugin] Gym cuda error: an illegal memory access was encountered: …/…/…/source/plugins/carb/gym/impl/Gym/TensorUtils.cpp: 156
PxgCudaDeviceMemoryDeallocate fail to deallocate memory!!

I was wondering why the problem is happening since I was just following the official document
